Parental report of behavioral and cognitive diagnoses in childhood-onset epilepsy: A case-sibling-controlled analysis

Area of Science:

• Neuroscience
• Child Psychology
• Genetics

Background:

• Childhood-onset epilepsy is associated with increased cognitive, behavioral, and psychiatric disorders.
• Some comorbidities may be linked to underlying structural or metabolic issues.
• The specific association in epilepsy of unknown or presumed genetic origin requires further investigation.

Purpose of the Study:

• To determine if cognitive, behavioral, and psychiatric disorders are more prevalent in young people with epilepsy of unknown or presumed genetic cause compared to sibling controls.
• To assess the association between epilepsy and these disorders in the absence of known structural or metabolic insults.

Main Methods:

• A cohort of 217 cases diagnosed with epilepsy (Connecticut Study of Epilepsy, 1993-1997) and 217 sibling controls were analyzed.
• Parental interviews were conducted 8-9 years post-diagnosis to collect information on cognitive, behavioral, and psychiatric outcomes.
• Statistical analyses, including odds ratios (OR), were used to compare cases and controls.

Main Results:

• Children with epilepsy were significantly more likely to be reported as slow learners (OR=4.6, P<0.001).
• Language disorders were more common in children with epilepsy (OR=5.8, P<0.001).
• Self-injurious behaviors, excluding suicide attempts, were also more frequent (OR=5.5, P=0.013).

Conclusions:

• Epilepsy of unknown or presumed genetic cause in children is strongly associated with learning difficulties, language disorders, and self-injurious behaviors.
• These findings underscore the significant non-seizure related burden in childhood epilepsy.
• Further research is needed to understand the long-term prognosis and impact of early-presenting conditions into adulthood.
